ROTARY SWING.

SPECIFICATION forming part of Letters Patent No. 642,883, dated February6, 1900.

Application filed December 24, 1898. Serial No. 700,203. (No model.)

Y?) a/ZZ whom t muy concern:

Beit known that I, CORNELIA SnoANn, a citizen of the United States,residing at Merrifield, in the county of Fairfax and State of Virginia,have invented certain new and useful Improvements in Rotary Swings, (asafe amusement for children and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it apperta-ins to make and usethe same, reference being had to the accompanying drawings, forming apart of this specification.

This invention relates to new and useful improvements in revolvingswings, and has for its object to provide a simple and durableconstruction for the amusement of children.

The invention consists in a pole rising from the ground, where it isheld in a vertical position, and providing a suitable frame at the top,adapted to turn thereon, and from the outer ends of which are suspendedsuitable ropes and cross-bars for seats, upon which the children arecarried.

It further consists in the general construction and arrangement of theparts to be hereinafter described and claimed.

Referring to the accompanying drawings for a better understanding of myinvention, Figure I is a perspective view of my improved swing. Fig. 2is a plan view of the supporting-frame; and Fig. 3 is a cross-section ofthe top of the pole, taken through the cap and supporting-frame,showingthe ball-bearings and the manner of carrying said frame.

A represents the bar, which may be of any suitable size and height,which isadapted to be secured and supported in the ground in an uprightposition. At the upper end of this pole there is tted the cap B, havingthe bolt C rising from the center thereof, and the ballbearing seat a,formed in the upper surface around said bolt.

D represents the supporting-frame, which, as seen in Fig. 2, is providedwith the aperture l), adapted to fit over the bolt C, and having thearms c f extending in opposite directions and perforated to receive theropes E F. In the lower face of this supportingframe there is provided acircular groove g, arranged to register with the seat or groove a,

within which the balls h are located to carry the supporting-frame D andto form a ballbearing for the easy rotation of said frame.

The ropes E F are secured at their upper ends to the arms c and fof theframe and extend downward at a suitable distance above the ground, wherethey are connected by crossbars or seats II I J, which are of variablelengths and arranged above each other, as shown in Fig. l, toaccommodate three or more children. The arrangement of the ropes andseats form ladders upon opposite sides of the pole, and when thechildren are fixed in their respective seats the one nearest the groundstarts the swing in its course around the pole until sufficient speed isgained to cause the bodies to swing out at a slight angle to the pole byvirtue of the centrifugal force.

As a means for preventing` the supportingframe D from escaping I providea holding-A nut m, arranged to engage over the upper threaded end of thebolt C.

As shown in the drawings, the seats are secured to the ropes byproviding holes through the ends thereof, through which the ropes arepassed, and when the proper position is obtained the said ropes areknotted, as shown at n. It will be apparent, however, that othersuitable means may be employed Without departing from the spirit andscope of my invention. v

From the foregoing it will be obvious that some slight modifications maybe made in the general construction and arrangement of the parts withoutmaterially affecting the results, and I desire to have it understoodthat while the form shown and described is preferred I do not wish tolimit myself thereto.

Having thus described my invention, what I claim is- In a revolvingswing, the pole A supported in an upright position, and the cap B havingthe bolt C rising from the center thereof, said cap fitting onto theupper end of said pole and being provided with a ball-bearing seat aformed in the upper surface around said bolt; in combination with thesupporting-frame D provided with an aperture b adapted to iit over saidbolt and having perforated arms e, f extending in opposite directionsfrom the IOO center, said plate being grooved :Lt g to regof said ropesat different heights und adapted ister with the ball-bearing seat a, theballs h to form seats, substantially as described. 1o arranged to fitWithin said seat and adapted In testimony whereof I aflix my signatureto support said frame, the nut m on the upiu presence of two witnesses.
